Last.



T0 all whomft m ay concern Be it known that Groen E. Ennemis, a citizen of the United States, resicling at Stoughton, county of Norfolk, Commonwealth o Massachusetts, have inventori certain new and useful improvements in Lasts, of which the following is a specication.

This invention relates to transverseiy xii vided lasts, and particularly to a tivo part last in vwhich the last parts move on each other with a hearing formed by a divitiing cut.

My present invention involves certain irnprovements over the device of my prior Patent No. 535,315, granted March 5, 1895, to which reference is made ,as illustrating the particular .type involved herein. The device of my prior patent While in the main satisfactory and an improvement over the earlier structures of the art, was nevertheless open to vseveral objections, which my present invention overcomes, as Will appear hereinafter.

lt sh ould he pointed outQat the outset that one of the most diilicult Vproblems in lasts of this type has been in the adiustinent of the last parts. if the last parts are drawn up so tightly as to "stick, the friction de 'velopecl makes it diicult anti sometimes impossible to fbreak clown the last so that the last often has to loe talren apart and readjusted. This invariably resulted; in the spoiling of the shoe on that last so that it had to he thrown away. is usually thrown away so that the loss is' really double.l If on `the other hand the last parts are not clrawn up tightly ener-.gh

a condition equally as had is reachecl.

When it is considered that the pressure and strain to which the last is suhjecte inv some of the shoe operations as for example in the sole leveling nfiachinesisl often suiicient to split'a last, it is obvious that .any unneces# sary play or looseness at the union will soon cause the last to break down. It will therefore he seen that this matter of adjustment L Then, too, the last of the last to wear away at the piv.

. iinother 'source o dicultyin'lasts this type has been in the tentlency of th'c vool whenever slack rlevelopeti, or to spl?? colere@ the excessively heavy pressure, to Xvhi last is subjected during the shoe op Asis Well known, this pressure is main directerlv upon lthe heel part a. consiolerahle amount falls on the la itself. The spindle soclret in Whit jack spindle enters is Usually prete a- Inetallic thimole having a closef end, outoften the pressure is so greet te lore-air this closecl end through and. split the 7c last. Various expedients have been fle- 'vised in the eort to prevent this splitting ole contact piece in the vicinity of ble has heen the most efective. This com 75' 'applied and in these drawings: `ligure is one of extreme importance;A The acliustment must be perfect `with no latitufie for error either Way. y

.it is therefore one of 'the ohjects of my present invention to provide a ividetl last in Whh a pedetermined ajustment of the of the last, of which the insertion of a sine,

the thimtact piece has been located in any variety ci? positions relative to the spindle socket andi. has been of any number of different si'aes 'and material. l have found however, that' hy positioning a simple Wootlen or iihroiis plug below the spindle and in the ciirect vertical line of thrust of the spinrile, very effective results may he had. The rein ofl the plug preferably runs longitn-:iinaiiv 'so as to present maximum resistance. y
